Less than 80 min. You said you have the LP spring and cap screw installed right? It's easy enough to make a simple u type manometer to measure the pressure using some plastic tubing, a ruler, and some scrap wood. Without a manometer, you can use the valves NG to LP conversion instructions to get the pressure pretty close to 10" WC, which IMO would be a decent place to start. Here's an excerpt-

VR8200C,P and VR4200C,P gas controls cannot be converted.
To convert control from one gas to another:
1. Turn off main gas supply to the appliance.
2. Remove the regulator cap screw and pressure regulator
adjusting screw. See Fig. 2 or 3.
3. Remove the existing spring.
4. Insert the replacement spring with the tapered end
down. See Fig. 4.
5. Install the new plastic pressure regulator adjustment
screw so that the top of the screw is flush (level) with the top
of the regulator. Turn the pressure regulator adjustment
screw clockwise six complete turns. This provides a
preliminary pressure setting of about 10.0 in. wc
